2018 Workshop Agenda

REGISTRATION CLOSED - We are sorry, but the maximum number of participatants for the 2018 workshop has been reached. If you are interested in being placed on a waiting list, send an email to requesting to be added to the waiting list. The training materials we use during the workshop are designed for you to study at your own pace and are available at the following link for 2018:

A 4 day HYSPLIT workshop will be given June 12 - 15, 2018, at the NOAA Center for Weather and Climate Prediction (NCWCP) in College Park, Maryland. The workshop will be focused on the use of the model on the PC/Mac and its applications.

  • Registration Opens: March 26, 2018 ~1600 UTC (12 pm Eastern Daylight U.S.) - Registration will be handled with an online registration form on this web page. There is a limit of 24 attendees. If you would like to attend remotely via GoToMeeting, see below under Remote Access.
  • Registration Closes: May 13, 2018 - but if registration reaches capacity (as it usually does), it will close early.

Please contact with any questions.


The first day of the workshop will be geared for those who have never used HYSPLIT previously. Participants will be given an overview of the model GUI, meteorological display programs, and simple examples of trajectory and dispersion model simulations. In subsequent days, participants will be provided an extensive hands-on training on how to solve atmospheric dispersion problems and several real world examples of increasing complexity.

The workshop will composed of some theory, examples, and hands-on approaches, and the class will be made up of both new and experienced users. A background in meteorology will be helpful for understanding the theory, but is not required.

Space is limited to 24 people and pre-registration is required. There is no fee for the workshop, however participants are responsible for their own travel expenses and arrangements.

Remote Access

The maximum number of available spots for remote access has been reached, so no other requests can be honored.

Computer and HYSPLIT installation

All participants should bring a laptop PC or a Mac, preferably with a mouse to help with the inputs. We strongly recommend installing HYSPLIT prior to attending the workshop as you will need Admininstrator privileges on your laptop to install portions of the software. Failure to have these privledges will preclude you from running the model examples on your laptop during the workshop. There are no requirements on the type of laptop, however we will be doing some intensive computations so a rather fast processor is recommended to keep up with the rest of the class. Instructions for downloading and installing the version of the model for the workshop will be given to the participants via email prior to attending the workshop.

Training materials

For those that cannot attend the workshop in person or will be viewing the GoToMeeting, all the materials that will be used in the training are available online and are designed to be self-pacing with all the graphics and examples needed. The 2018 tutorial is available at:

Model Download

The current trial version of the model (the registered version can also be used but is not required for the workshop) can be downloaded from:
